如何在Windows上构建Python Sybase模块?

Question

我试图在Cygwin上构建python-sybase模块，但它似乎不起作用。它似乎开始编译，然后开始抛出以下错误:

$ python setup.py install
running install

running egg_info

我也尝试过mingw32编译器，但我得到这个错误:

有没有人能够成功地在Windows上编译Python-Sybase ?如果我不能在Cygwin中做到这一点，是否有一种简单的方法可以让我在Cygwin之外构建这个(使用免费编译器)?

Answer 1

如"安装"页面所述，您应该能够使用免费的(Microsoft) Visual c++ 2005/2008 Express Edition在Windows上构建Python-Sybase。

Answer 2

我遇到了mingw的问题，"undefined reference.."，于是下载了(Microsoft) Visual c++ 2008 Express Edition，并进行了编译…
